Nuclear weapons are explosive devices that derive their destructive force from nuclear reactions, either fission (the splitting of atomic nuclei) or fusion (the combining of atomic nuclei). When detonated, these weapons release enormous amounts of energy, resulting in massive explosive power, intense heat, and lethal radiation.
